Energy efficient storage six months away

Businesses will be able to buy storage products that offer energy efficient storage within six months.

Speaking to Computer Weekly at the start of the Burton Group analyst conference in Barcelona, Drew Reeves, research director at Burton Group, said, "Storage infrastructure used in datacentres will run more efficient disc drives."

The storage industry body, SNIA, has been working on a green storage initiative. Products coming out of this programme will help businesses to implement tiered storage using low-cost Serial ATA disc drives as to cache data rather than store data directly on energy efficient SAS drives.

Reeves said this configuration would enable the datacentre manager to reduce storage electricity consumption.

"SAS drives consume between five and 10 watts per disc. By using Serial ATA drives as a cache to store the data first, there is no need to run the SAS drives continuously. They only need to be powered when the data stored in the cache has to be written to the disc," said Reeves.
